Signals are consulted strongest-first (see fct_orientation.R): an explicit user choice, then where the two armies sit, then coordinate labels, with legality only breaking a remaining tie. A wrong 180-degree flip scrambles the whole board, so the chosen orientation is also reported back to the UI along with the signal that decided it.
